A method and a system for establishing a route of an unmanned aerial vehicle are provided. The method includes identifying an object from surface scanning data and shaping a space, which facilitates autonomous flight, as a layer, collecting surface image data for a flight path from the shaped layer, and analyzing a change in image resolution according to a distance from the object through the collected surface image data and extracting an altitude value on a flight route.
Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
10. The system of claim 9, wherein the collection unit obtains the point cloud onto which a light detection and ranging (LiDAR) pulse is projected via a LiDAR device of the aircraft.
This invention relates to a system for capturing and processing point cloud data using a LiDAR device mounted on an aircraft. The system addresses the challenge of accurately obtaining and analyzing three-dimensional spatial data from airborne platforms, which is critical for applications such as mapping, navigation, and environmental monitoring. The system includes a collection unit that acquires point cloud data by projecting LiDAR pulses onto a target surface. The LiDAR device emits laser pulses, which reflect off objects and return to the sensor, generating precise distance measurements that form the point cloud. The collection unit processes these reflections to construct a detailed 3D representation of the scanned environment. The system may also include a processing unit that further analyzes the point cloud data to extract features, classify objects, or generate terrain models. The invention improves the accuracy and efficiency of airborne LiDAR data acquisition, enabling real-time or post-processing applications in various fields. The system is particularly useful for high-resolution mapping, autonomous navigation, and environmental monitoring, where precise spatial data is essential.
11. The method of claim 7, the layer shaping unit generates a plurality of two-dimensional (2D) layers on the space.
12. The method of claim 8, the shaping the space map unit matches a GPS coordinate to the autonomous navigation map, processes an altitude value of an image from the autonomous navigation map, and corrects, based on the processed altitude value, an altitude value measured by a sensor.
15. The method of claim 13, wherein at least one of the way points is a point at which the unmanned aerial vehicle performs a mission assigned thereto.
